Product details
Overview
LT1352CN8#PBF from Analog Devices (formerly Linear Technology) is a dual, low-power, high-speed operational amplifier in an 8-lead PDIP package. It delivers 3MHz gain bandwidth, 200V/µs slew rate, and 250µA supply current per amplifier at ±15V, enabling precision signal conditioning in battery-powered instrumentation and photodiode preamplifiers.
For engineers reviewing the LT1352CN8#PBF datasheet, LT1352CN8#PBF pinout, LT1352CN8#PBF application, or LT1352CN8#PBF equivalent, key selection criteria include input offset voltage (≤0.6mV), capacitive-load stability (C-Load™), unity-gain stability, output swing into 1kΩ (±13V), and operation across ±2.5V to ±15V supplies.
Technical Context
The LT1352CN8#PBF employs a proprietary voltage-feedback topology with current-feedback slewing behavior, using complementary bipolar processing to achieve high slew rate without sacrificing DC precision. Its matched high-impedance inputs and internal RC/CC compensation network ensure stability with any capacitive load.
Each amplifier features independent input stages with NPN/PNP bias cancellation, enabling low input bias current (≤50nA) and low input offset current (≤15nA). The device is specified over –40°C to 85°C and supports rail-to-rail input common-mode range up to ±13.5V with ±15V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3MHz at ±15V - enables stable closed-loop operation up to ~300kHz in unity-gain buffer configurations. |
| Slew Rate | 200V/µs at ±15V - ensures full-power bandwidth of 3.2MHz for 10V peak signals, critical for fast transient response. |
| Supply Current per Amplifier | 250µA at ±15V - allows dual-channel amplification in ultra-low-power systems like portable medical sensors. |
| Input Offset Voltage | Max 0.6mV at ±15V - supports 12-bit accuracy in 5V-span data acquisition without trimming. |
| Output Swing into 1kΩ | ±13V at ±15V - provides >86% rail-to-rail swing, minimizing headroom loss in single-supply-derived bipolar rails. |
| Capacitive Load Stability | C-Load™ certified - drives unlimited capacitive loads without external compensation, simplifying PCB layout for ADC drivers and cable interfaces. |
| Input Noise Voltage | 14nV/√Hz at 10kHz - suitable for low-noise photodiode and strain-gauge amplification where signal levels are sub-mV. |
Pinout & Package
LT1352CN8#PBF is housed in an 8-lead plastic DIP (N8) package with 0.300-inch width, compatible with through-hole assembly and prototyping breadboards. Thermal resistance θJA = 130°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT A | Amplifier A output | Capable of ±13V swing into 1kΩ; drives capacitive loads directly without oscillation. |
| 2 - –IN A | Inverting input A | Differential input voltage rating ±10V (transient only); requires balanced source impedance for minimal offset drift. |
| 3 - +IN A | Non-inverting input A | Common-mode range extends to ±13.5V at ±15V supplies; supports wide dynamic range sensor interfacing. |
| 4 - V– | Negative supply rail | Connects to system ground or negative rail; must be bypassed with 0.01µF–0.1µF ceramic capacitor near pin. |
| 5 - V+ | Positive supply rail | Accepts ±2.5V to ±15V; supply rejection ratio ≥90dB minimizes noise coupling from noisy rails. |
| 6 - +IN B | Non-inverting input B | Electrically identical to Pin 3; enables dual-channel synchronous signal processing in compact layouts. |
| 7 - –IN B | Inverting input B | Matches Pin 2 performance; channel separation ≥101dB prevents crosstalk in multi-channel filters. |
| 8 - OUT B | Amplifier B output | Independent output stage; supports simultaneous driving of separate loads without interaction. |
Key Features
| Feature | Design Value |
|---|---|
| C-Load™ capacitive-load drive | Stable with unlimited capacitive loads - eliminates need for isolation resistors or external compensation networks. |
| Unity-gain stability | Operates stably at AV = 1 without external feedback compensation - simplifies buffer and follower designs. |
| Low input bias current | ≤50nA max - preserves signal integrity in high-impedance sources like photodiodes and piezoelectric sensors. |
| Wide supply range | ±2.5V to ±15V - supports both low-voltage portable systems and industrial ±12V legacy rails. |
| Fast settling time | 1.25µs to 0.01% for 10V step - meets timing requirements in multiplexed data acquisition with >100kSPS throughput. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1352CS8#PBF | Same electrical specs; SO-8 surface-mount package (θJA = 190°C/W vs 130°C/W for N8). | Required for automated SMT production; unsuitable for hand-soldered prototypes or breadboard evaluation. | Select when board space is constrained and reflow assembly is used; verify thermal margin under worst-case load. |
| LT1351CS8#PBF | Single-channel, includes shutdown mode (IQ < 1µA off); 2.5MHz GBW, 150V/µs slew rate, 180µA IQ. | Used where power gating or channel count reduction is needed; not pin-compatible with LT1352CN8#PBF. | Choose for ultra-low-power standby modes or when only one amplifier is required per function block. |
Compared with LT1352CS8#PBF, the LT1352CN8#PBF offers superior thermal performance in through-hole layouts but requires larger PCB area; versus LT1351CS8#PBF, it provides dual-channel integration and higher slew rate at the cost of no shutdown capability.

FAQ
What is the maximum operating temperature range for LT1352CN8#PBF?
The LT1352CN8#PBF is rated for operation from –40°C to +85°C and is guaranteed to meet all specifications across this industrial temperature range. Its plastic DIP package has a maximum junction temperature of 150°C, and thermal design should account for θJA = 130°C/W under typical PCB conditions. Derating is recommended above 70°C ambient when driving heavy loads.
Does LT1352CN8#PBF require external compensation for capacitive loads?
No, the LT1352CN8#PBF incorporates C-Load™ technology and is explicitly designed to remain stable with any capacitive load - including cables, ADC input capacitance, or long PCB traces - without external series resistors or compensation capacitors. This eliminates phase-margin tuning and reduces bill-of-materials count in high-fidelity analog paths.
Can LT1352CN8#PBF operate from a single +5V supply?
Yes, the LT1352CN8#PBF supports single-supply operation down to +5V total (i.e., V+ = +5V, V– = 0V), though its input common-mode range is limited to 0.5V to 3.5V and output swing to ±3.4V into 500Ω under ±5V dual supply. For true single-supply use, biasing inputs within the valid common-mode window and using rail-splitter references is required.
What is the input bias current polarity behavior of LT1352CN8#PBF?
The LT1352CN8#PBF uses complementary NPN/PNP input transistors that provide first-order bias current cancellation. As a result, input bias current polarity (positive or negative) depends on beta matching variations and may differ between units; however, input offset current remains tightly controlled at ≤15nA. Balanced source impedances at both inputs minimize offset voltage drift.
How does LT1352CN8#PBF compare to LT1352CS8#PBF electrically?
LT1352CN8#PBF and LT1352CS8#PBF share identical electrical specifications - same gain bandwidth, slew rate, noise, offset, and supply current - differing only in package: N8 (PDIP) vs S8 (SO-8). The N8 version offers lower thermal resistance (130°C/W vs 190°C/W) and is preferred for prototyping, through-hole assembly, and thermally demanding environments.
